I just bought Microchip C18 compiler and use it along with MPLAB 6.30. I do file editing using CodeWright and compile and debug using MPLAB (Can you debug under CodeWright or UltraEdit?). I found that MPLAB crashes about once every 5 minutes. It is very annoying. I don't know if it is related the CodeWright or not, but when I use MPLAB to do the editing, it doesn't crash anymore (and I can't stand editing using MPLAB!!!) Anyone has any problem like this? Please help! Thomas. --------------------------------- Do you Yahoo!? Exclusive Video Premiere - Britney Spears -- http://www.piclist.com hint: The PICList is archived three different ways.
